thanks for the advice. I got this seat (the convertible type) over a year ago at my baby shower. Now that my son has outgrown his infant seat, I'm ready to install it and can't find the owner's manual!...But I will track down that info at a saftey inspection or call Britax.

I had heard before that it was behind the driver, and I know in our truck it is...in fact it says not to put a car seat in teh center. But in our Jeep it says to put it in the center and I know some cars say to....it is usually listed in the owners manual where the safest place is. I do know that they are never supsed to be placed in the captians style seats for a number of reasons. I hope this helps some...I know its not a real answer, but if you don't have an owners manual I know that if you go to a car seat safty inspection they have a book where they can look it up, or you can call a dealer for whatever car you have if you don't have an owners manual and they should be able to tell you what the manufacturers guidelines are.
